Effect of Wood-Based Panels and Varnish Types on VOC Emissions in Furniture Production

Abstract

This study investigated the effects of varnishes on VOCs emissions from wood-based panels of standard particle panels (PB) and medium density fiber panels (MDF) which are covered by beech veneer and varnished by three different types of varnishes. The highest value was 624,90 ppm for Toluene, while the lowest was 0,30 ppm for Para xylene in respect to the Particleboards which were covered by beech veneered and varnished with cellulosic varnish. However, samples of beech veneered and varnished with synthetic and polyurethane varnishes yielded less gas emission than cellulosic varnish. The samples of MDF, covered with beech veneer and varnished polyurethane varnished yielded gas emission more than the synthetic (100%) and cellulosic varnishes (220%). All values show that gas emission reduces its effect within time in respect to the manufacturing time, after drying period, 15- and 30-days measurements.
